Patented Sept. 18, 1934 UNITED STATES PATEN mm==s==== rte My invention relates-to a record device embodying a holding member such as a tray or drawer, together with a series of cards or record sheets and means for detachably mounting the ".l cards or record sheets in the tray or drawer, so that they may be turned back and forth like the leaves in a book, to make either side of the card available for placing facts or figures thereon. The device is particularly useful for forming a tray unit for use in a filing cabinet such as that disclosed in my oo-pending application for patent, Serial No. 459,683. and filed June 7, 1930, although the present case is not limited in its application to any particular cabinet or structure.

One object of the invention is to provide a simple and inexpensive form of tray, drawer or holder which may be made of sheet metal and which is subject to quantity production with suiiicient degree of uniformity to make the device commercially practical. This tray is formed with laterally and inwardly projecting flanges extending inwardly from opposite sides of the tray to form guiding members or tracks with which the followers for the top and bottom of the row of cards co-operate and by which they are guided and with which the followers lock.

Another object is to provide a trackway in the tray with which the members for securing the individual cards or sheets in hinged relation to the tray, may slide andwith which said members are detachably engaged to permit them to be individually removed or detached from the tray. lhese card holding members have a sliding engagement with the guide in the tray and they are removable from the guide to allow the use of a greater or lesser number of card holding members. The card holding members themselves are adapted to secure the cards or recording members detachably in the tray toibe folded back and forth like leaves of a book and in such manner that the cards may be quickly attached to or detached from their holders, each card independent of the others, in order that they may be removed if desired, for the purpose of having notations made thereon, or for transferring a card from one tray to another. Thecard holders are of very simple and inexpensive con,- struction, being made of bent wire, and therefore they may be very cheaply produced in large quantities and with very simple wire bending machinery. As they are preferably made of wire, they may have the necessary resiliency and flexibility to permit a portion to be sprung or moved for the purpose of attaching the cards to and detaching them from their individual holders without disturbing the remainder of the cards in the tray and without injury to the cards themselves. I

Another object of the invention is to provide 3 a very simple follower for the upper or topend of the stack of cards in a tray, the follower having a stiff or metal leaf adapted to fold down over the cards; and this follower is provided with a very simple and inexpensive locking device which cooperates with the side tracks of the tray to lock the follower in different positions of adjustment lengthwise of the tray in accordance with the stack of sheets held by I thetray. The locking device of this follower is of the most inexpensive construction, which is a desirable factor in view of the fact that a recording system may employ hundreds or even thousands of the trays with followers. V Another object is to provide a bottom stop device at the bottom of the stack of cards, having telescopic parts which permit parts of the bottom stop to be slid in relation to each other against the resistance'of aispring in order to release the pressure on the stack in a simple manner to allow any individual card to be removed from the tray.

Other objects to be accomplished, and advantages of the invention will be set forth in the following detailed description, 3

I will first describe the form of my invention shown in Figures 1 to 11 inclusive. In this construction I have shown a member which may be a tray, drawer or other type of receptacle but which I will here referto as a tray without intending to limit the invention to a particular type of container. This tray 1 includes a bottom 2 having side and end walls 5, 6 preferably of single thickness, formed by bending up the margins of the metal at right-angles to the bottom wall. There is astrip of metal bent reversely upon itself to form an outer wall 3 and a substantially parallel inner wall 4 to enclose and engage the inner and outer surfaces of the side and end walls 5, 6 of the tray to reinforce the same and to carry the side rails hereinafter referred to. The strip of metal of which the walls 3, 4 are formed extends preferably around both sides and both ends of the tray, the opposite ends meeting as shown at 7 in Figure 1, or in other words, the strip of metal forming these walls is bent into rectangular shape and is pressed over the side and end walls of the tray, so that it becomes permanently attached thereto. This is a simple method of constructing the tray with reinforced side and end walls and with the tracks carried by the reinforcing member. The bottom portions ofthe inner wall 4 of this strip is bent inwardly, preferably at right-angles, to form the tracks or guideways 8 which are provided to extend adjacent the two side walls 5 of the tray, but these tracks may be omitted from the reinforcing strip where the latter extends across the top and bottom ends 6 of the tray, as shown in Figure 1.

These flanges or tracks 8 project inwardly in opposite directions from the side walls of the tray and are spaced above the bottom of the tray to provide spaces 9 in which the locking members of the followers may move and in which the card-holding members, in one form of the device may also travel and be guided. These flanges or tracks are provided with apertures 10 disposedat close intervals along the tracks and with the apertures of one track in horizontal alignment with the apertures in the opposite track; and with these apertures the top follower may be locked as will be set forth hereinafter.

In the form of the invention shown in Figures 1 to 11 inclusive the cards, sheets or other recording members may consist of a folded blank 11 shown in Figure 10 which is folded upon itself along the edge 12 to provide two parallel leaves and I have shown notches 13 out along the folded edge 12 to receive a portion of the card holder therethrough. The card holders illustrated in this form of the invention consist of a long, thin member, preferably wire, and coiled into the shape illustrated in Figure 9. The wire has one. end 14 extending crosswise in relation to the tray, and this is followed by a longitudinally extending portion 15, and the latter is followed by a second crosswise portion 16. The latter is followed by a longitudinally extending portion 17 which is itself followed by a crosswise portion 18 extending to a point adjacent the end of the portion 14. These several parts just described constitute substantially a rectangle which forms the base of the card-holding member.

From the portion 18 the wire extends upwardly at 19 or vertically away from the plane of the rectangle and the wire then extends horizontally at 20, this portion of the wire being sufficiently long to project substantially the width of the tray, and one end is free to receive the card thereon.

In the form of tray shown in Figure 1 there is a substantially Z-shaped member consisting of a track or flange portion 21, a short vertical portion 22, and a bottom, horizontal portion 23, the latter being riveted or otherwise secured against the top face of the bottom of the tray, so that the flange or track portion 21 projects toward the track member 8 at one side of the tray and in the same plane therewith. The track 8 and the member 21 therefore cooperate with the bottom of the tray to form a guideway 24 to receive the rectangular portion of the card holders which are shown in Figure 9.

The card holders may be applied to the tray by presenting the rectangular base member 1418 to'the guideway 24 by turning the card holder to an oblique or nearly vertical position which will permit the ends of the rectangular base to pass between the members 8, 21 and below the plane of these members, after which the card holder is turned into a horizontal position crosswise of the tray, as shown in Figure l, whereupon the ends of the rectangular base of the card holder will pass under and be held by the members 8, 21, so that the card holder cannot move-laterally, but it can be slid lengthwise of the tray, the base of the card holder travelling in the guideway 24.

It will be apparent that when a number of card holders have been placed in the guideway 24 the several holders may be pressed with their bases one against the other, and due to the vertical depth of the several rectangular bases of these holders the lateral card-supporting arms 20 'will be held in slightly spaced relation, one from the other, so that the cards mounted on these arms will be slightly spaced lengthwise .of the tray.

Where the cards are of the double or folded type, as shown in Figure 10, each card may. be attached to a holder by lifting up the free end of the arm 20 of the card holder and presenting the card, so that the end of this arm passes first into the left hand opening 13 at the folded edge of the card, and the arm then passes along inside the card or between the leaves thereof, until the free end of the arm 20 is passed out through the second aperture 13, at which time the card will be disposed crosswise of the tray and it will be hingedly supported upon the arm 20 of the card holder. The card may be swung back and forth like the leaves of a book, with either wall or fold of the card accessible for making indicia thereon. The card holders above described are, preferably made of a resilient or spring wire to permit the free arm 20 to be bent up for receiving the card and for removing it therefrom, and the natural resiliency of the holder will cause this arm to move downwardly when a card has been attached, so that will lie in its correct position within the tray, as shown in Figure 1. The upwardly extending or offset portion 19 of the card holder permits the arm 20 to normally lie spaced above but substantially parallel with the bottom of the tray, so that the cards may rest on the tracks 8, if desired.

The top follower or the member for engaging the top of the stack of active sheets in the tray to hold the card holders in orderly condi tic-n is constructed as follows: There is a cross member or bar which may be formed of fiat metal, and it is shown as provided with a bottom member 26 (see Figure 6), from which extends upwardly a portion 27 and from there the metal isbent inwardly or horizontally at 28, thence upwardly at 29, and at the top it is bent into a loop 30 to form a socket for the hinge rod 31. The metal is then bent downwardly at 82, preferably parallel to and spaced from the wall 29 and at the bottom the plate is then bent horizontally as shown at 33 toward the portion 27. This formation provides a pocket or recess 34 in which the locking member is enclosed and in which it is adapted to move. There are pins or, rivets 35 passing through the vertical portions 29, 32 of the follower bar and disposed on opposite sides of the center of the bar to form iulcrunis against which the locking mem-- ber may be flexed. The upper portions of the follower bar, i. e., the parallel members 29, 32 and the eye 39 are cutaway or omitted. adjacent the central line or" the follower, as shown at 36 in Fl me 1, as well as in Figures 4 and 5, to provide a space for th insertion of the fingers, as shown in Figure 5, for the purpose of operating the locking device. This lock ng device consists of a bowed wire or spring 37 which lies normally against the top of the pocket 34 of the follower bar and which projects towards opposite ends of this bar, passing over the tops of the two supporting pins 35; and the opposite ends of this spring are bent downwardly as shown. at 38 so that they pass through apertures 3Q, 48 in the bottom plates 33, 26 of the follower bar such positions that they may caused to register with the several apertures it along the side tracks 8.

In Figure 4 I have shown the locking spring released, which case the ends 38 project through the apertures 39, 40 and into the apertures 10 of side tracks with which they re .lter and n this condition the follower is loosed in finite position within the tray. To release the locking device in order to permit the follower to be moved up or down within the tray, the operator presses with the finger on the middle portion of the locking spring 37, as shown Figure 5, and this downward pressure the middle of the spring causes the end portions to rise by reason of the pivotal action of the spring on the two pins 35. This causes the locking portions 38 of the spring to rise within the apertures 39, 40 in the follower bar sufficiently to retract the ends'from the apertures 10 of the tracks 8 and while this condi tion exists the follower may be moved along the tops of the tracks or lengthwise of the tray.

There is a leaf plate 41, preferably of metal and corresponding substantially with the size of one of the cards, and this plate has a central cut-out portion 4-2 and the top edge of the plate on oppositesides of the cut-out portion is looped to provide ears 43, which surround the hinge pins 31 which are mounted in the 30 on the top edge of the follower bar, in Figures 1, 4, 5 and 6. This leaf, which is designed to hold the cards down in closed position as shown in Figure i when the tray filed away, is adapted to be turned upon its hinge and to be reversed or turned over to form a support or platen to permit any of the upper cards of the stack to be placed against it and to be used while writing on a turned-back card.

The stop for the bottom or lower end of the row of cards is constructed as follows: There are two plates, to wit, an upper and a lower plate 44, adapted to telescope in relation to each other, and for this purpose the plate 45 is provided with turned-over marginal portions 46 to partially enclose and guide the upper plate 44- which telescopes in relation to the lower plate. The bottom edge of the lower plate is turned over or bent at right angles, as shown at 47 and it is of sufficient depth so that when it rests against the bottom of the tray it will hold the lower end of the bottom plate 45 of the device elevated to a plane adjacent the top edge of the tray, as shown in Figure 19. At the top edge of the upper plate 44 of the stop device the metal is turned over to form an eye 48 in which is enclosed and gripped a laterally extending rod 49, the latter being of resilient material such as wire, and the free ends of this wire project laterally and are adapted to engage the under sides of the two tracks 8 at opposite sides of the tray for the purpose of securing the stop device in position and for guiding it in relation to the tray. There is a loop spring 50 pressing against the bottom wall 47 of the stop device and the upper end of this loop spring presses against a lip 51 which is formed from the metal of the upper plate 44.

This spring normally holds the stop device in extended position so that the upper of the upper plate 44- forms an abutment for the bottom of the row of card holders.

The top plate 44, however, may be pressed downwardly by hand. against the resistance of the spring 50 to partially telescope the plates of the stop device, thereby moving the top edge of the top plate 44 from the lowermost card holder of the stack in order to permit any one of the card holders to be removed from the tray.

I have shown a very simple device for att ching the tray to a foldable cabinet device such as is shown in my Patent No. 1,925,?25, dated Eeptember 5, 1933. spring 52, the central portion of which rests against and is secured to the end wall of the tray as shown at 53 in Figure l and from 0pposite sides of the point of attachment the spring bows outwardly away from the flange of the tray and thence backwardly at 54 toward the flange of the tray, each end of the spring being provided with a pintle 55 which pinties move through apertures in the end flange of This. consists of a bowedlll) the tray so that either pintle may engage in a locking aperture in one of the tray-holding arms 56 forming part of the cabinet. device. The opposite end of the tray is provided with an aperture to receive therein the fixed pintle 57 on the opposite end of the tray holder 58. To attach the tray to a tray holder the upper end of the tray is presented so that the pintle 57 is received in its aperture at one corner of the tray and one end of the bowed spring 52 is pressed upwardly by hand and the corner of the tray adjacent thereto is brought into position with relation to the tray-holding member 56 so that releasing the bowed spring it will cause the movable pintle 55 to move into the registeringaperture of the tray holder.

In this manner the tray is pivotally mounted in its holder whereupon it may be swung in relation to the holder like the'leaf of a book, as illustrated in my said patent. To release the tray from the holder it is only necessary to press upwardly on one end of the bowed spring 52 in order to release the pintle 55 from the tray-holder.

The operation of a device constructed in accordance with the form of the invention above described will be as follows: Any desired num ber of card holders will be applied to the tray below the top follower by inserting their rectangular portions between the track 8 and the member 21 so that the of the holders rest against the bottom of the tray between these track members, whereupon the card holder is moved into a'position crosswise of the tra which will cause the base of the card holder to lockingly engage under the members 8, 21. After the desired number of cardholders have been assembled in the tray, they are moved downwardly one against the other, until the lowermost one rests against the bottom stop device and each of the succeeding holders rests against the one next below it. When the desired group of card holders have been applied to the tray, the top follower is inserted so that the bar 25 rests on the'tracks 8 and the follower is moved downwardly until its crossbar 25 rests against the uppermost card holder. During this sliding movement of the top follower the finger is pressed onthe central portion of the locking spring 37 as shown Figure 5, in order to hold the locking ends 38 of the spring retracted.

When the top follower has been placed against the uppermost card holder the finger pressure on the locking spring is released and if the locking ends 38 are not in register with the set of apertures 10 in the guide tracks 8, the follower will be moved upwardly a slight extent until locking a set of apertures in the tracks, whereupon they project through the apertures and lock the follower adjacent the top of the row of card holders.

To apply a card to a holder the arm 20 of one of the holders is held raised by the fingers of one end while the card is presented to the free end of the arm, so that the end of the latter enters one of the apertures 13 in the bottom of the card, thence travels through the looped bottom edge of t re card and emerges again through the second aperture 13 adjacent the right hand side of the card shown in Figure 3. The arm 26 is then released and the card will be held in crosswise position within the tray and will be free to pivot on the arm 20 so that it may be swung back and forth like the leaves of a book. This operation will be carried on until cards have been applied to the several card holders to form a stack and the several cards will lie in overlapping relation, as shown in Figure 1. The plate 41 of the top follower which may be of heavy enough material to act as a weight, will rest on the stack of overlapping cards to hold them in proper position within the tray; The cards in the lower portion of the stack will overlap the bottom stop device to some extent.

When it is desired to examine any of the cards in the tray the plate 41 of the top follower is turned back on its'hinged pins 31 or away from the cards in the tra whereupon one side or face of the top card of the series will be exposed to View as well as marginal portions of all of the cards below the topmost one. If the card to be examined is found by suitable notation on its marginal portion, all of the cards above the same will be turned upwardly against the turned-back plate. 41 of the top follower to provide access to the card which is to be examined, or on which notation is to be made. If this is a card adjacent the top follower, it may be turned upwardly against the upturned plate 41 and the latter will serve as a platen if it is desired to write against the upturned card. If it is a card adjacent the bottom of the stack, the bottom follower may be used as a platen in writon the card. If it is desired to apply written matter to a card by means of a typewriter, the particular card may be quickly detached from the arm 26 of the particular'card holder whereupon the card may be placed in a typewriter and the desired matterwritten upon it. Afterwards, the card maybe returned to its holder in the same manner as hereinabove described. In the present construction the cards may be removed and returned to their holders very quickly, so that the time consumed is comparable with the removal of an index card in an open drawer, except that there is the further advantage that the cards are each held pivotally on their holders when they are in the tray.

If it is desired to remove any individual card holder or to insert an additional holder in any place in the row, either the top follower nay be moved upwardly, or if desired, if there is not suificient space for the upper. follower to be moved, the upper plate of the lower stop device may be pressed downwardly against the 0pposition of the spring 50 to provide enough space for swinging any one of the card holders into position to remove it from the guideway 24 or to provide a space for the insertion of an additional card holder. Such card holder may be removed orreplaced at any position in relation to the row, that is to say, the bottom card holder or any intervening card holder may be removed or replaced. When the removal or replacement has been carried out, the bottom stop device is releasedso that it is extended by the bowed spring 50 in position to cause the upper plate 44 to press against the lowermost card holder and retain the series in compact relation.

In Figures 12 to 16 inclusive, I have shown a modification of my invention in which the means for attaching the card holders to the tray is spaced from or centrally located'in relation to the side tracks. In this form of the invention the side tracks, as well as the top follower and the bottom stop devices may be of the same type as that previously described, so that they do not need to be again illustrated and described in connection with this form of the invention. There is a strip of bent metal riveted or otherwise attached to the bottom of the tray and preferably centrally located or in the median line of the tray.

This metal is curved or folded at its side edges, as shown at 61 to provide oppositely disposed fl nges forming a guideway 62 in which the attaching members of the card holders are adapted to be guided. In this form of the invention the card holders, formed preferably of bent Wire, are bent adjacent one end to provide the rectangular base 63 similar to and corresponding with the base of the holder first described; and these bases are adapted to be inserted into the guideway 62 by turning them obliquely in relation to the tray until they pass between the flanges 61 and rest against the bottom wall or" the strip 50 whereupon the card holder is turned so that the sides of the rectangular project under the flanges 61. The

wire of which the card holders are madeis bent upwardly from there-ctangular base, as shown at 64 and thence horizontally across the bottom of the tray towards one side at 65 where the Wire is looped around itself to form a spring portion 66. From there the wire extends in the form of a free arm 67 backwardly or reverse to the portion 65 and it extends acrossthe strip 60 and terminates at a point to the right of this track, as shown in Figures 12 and 13. If desired, the end of this bar may be looped to form an eye 68 to facilitate the insertion of the same through the apertures of the card. The cards used with this type of hol may be similar to the cards first described, and one of the cards is shown in detail in Figure 16. It con-v sists of a blank folded upon itself along the edge 69 and with suitable cut-outs or openings 70 to receive the free arm 67 of the card holder therethrough. The cards are applied to this type of holder by holding up the arm 67 with one hand applying the card so that the free end of the passes throughthe left-hand opening '29, thence the inside of the looped edge of the card and the free end or loop 68 passes downwardly through the second aperture "iii.

When'thus attached to the holder, the card is free to pivot from its lower edge upon the arm 67. In this type of holder the spring portion 66 provides greater elasticity for the arm 67 and allows this arm to be bent upwardly or away from the bottom of the tray to a considerable degree without permanently bending or distorting the card holder. In this construction the guide for the card holders is centrally located wi hin the tray instead of beingdisposed adjacent one of the tracks 8.

In Figures 1'? and 18 I have shown a single or oneleaf card with the card holder modified to receive it. In this case the card 71 is simply a single flat blank with a central cut-out portion F2 to avoid contact with the guiding plate 60. There are aperatures 73 to receive the arms of the card holder. The card holder may be formed of bent wire but in this instance the base of the holder consisting of the rectangular portion 74 is formed at the middle of the holder and it may be inserted into the same guide members 60, 61 as shown in Figures 12 and 13; From the base '74 both arms of the wire are bent upwardly as shown at 75 and the arms 76 extend outwardly in opposite directions from the base 74,

the ends of these arms being free. The card is applied to the holder by placing it so that the free end of one of the arms '76 enters one of the apertures 73 and the card is then slid along the arm until the free end of the other arm '76 can be entered into the other apertures '73; after whichthe card is moved baclrwardly until it lies on the holder centered as shown in Figure 17. This type holder is thus adapted for plain or single cards as distinguished from the folded cards. 7

In all forms of the invention the construction of the tray, the 'uiding members and the card holders is very simple and inexpensive so that an equipment for an extensive accounting department may be supplied at a reasonable price.
